Works as intended for a great price on this size!!

So far, they have worked really well with my existing AC system. In fact they have cut down the dust in my house by a big margin

Good price, Great Quality

These are really good filters and the price is good for the quality

Best price I've found for these ultra filters. Colds and flu are much decreased since starting to use these filters. Dust is minimal (for Nebraska). Would recommend it someone in your family has pets or allergies.
